You perform calculations and then use the results of those calculations to access $_POST variables ... it seems unlikely to me that that is really supposed to be in that way.

for example, you do:

$venzini_kinisis_1 = ($REQUEST['15']/$REQUEST['8']) * $REQUEST['1'];
and then later use this:
$POST['".$venzini_kinisis_1"']
as an argument in a function. There is no guarantee $venzini_kinisis_1 really exists as a key in $_POST

So how i should suppose to do it to be sure it exists as a key cause it supposed that exists.The form has already values in it ,numerical i mean.
